I went to watch women's tennis yesterday at the Roger's Cup in Toronto. Up until now, most of my photos have been of static subjects, and trying to shoot sports has definitely posed quite a challenge for me, not to mention I felt that I needed longer reach than my 55-200mm VR could provide. I understand that sports photography typically requires very expensive equipment, but this is probably something I would do only once in a while, so I defintely am not looking to invest money into lenses strictly for shooting sports. I was also undecided about which AF mode was best suited for sports. I normally use AF-S for my other shots, which allows me to lock focus on the subject and reframe for the desired composition. With moving subjects, this proved to be very difficult. I tried AF-C, which from my understanding will continually refocus as I follow the subject with the camera. My problem is that by doing so, I lose the ability to properly compose a shot as it will always establish focus using the active focus point (in my case, the center focus point). Anyways, please let me know what you think of my shots and any tips regarding AF settings and such that will help me with shooting action shots. Thanks in advance.
